With Google's event fast approaching on 4 October, the rumour mill is in full swing. We know we're going to get new 'made by Google' phones, which will drop the Nexus brand in favour of Pixel. However, there's going to be more to watch out for - everything is lining up for 4 October being a major turning point in Android's relatively recent history.

If the rumours are to be believed - and with so many different sources all pointing towards the same thing, you can probably believe them - Google will unveil not just a few new phones, but a new operating system altogether, dubbed Andromeda. And, just like we've been talking about for a long time, this is the operating system that combines Android and Chrome OS into a desktop/laptop operating system.

Why so many mentions of Nexus 9 specifically in tandem with Andromeda? We asked the same question, and from what we can gather, Google is testing the Chrome OS/Android hybrid on the tablet. An anonymous source has told us of users running early builds of Andromeda on the Nexus 9, but we have not been able to obtain direct confirmation from those users. Why would Google be testing Andromeda on the Nexus 9? We don't know.

But we do know that Andromeda is aimed at making Android better suited for devices like laptops, as well as 2-in-1s (like the unfortunately mediocre Pixel C) and perhaps tablets. Another interesting tidbit to note: it seems that the hidden free form window management feature that popped up in Nougat (but isn't user-facing) could appropriately see its debut with Andromeda. "SurfaceCompositionMeasuringActivity.java" mentions "Detect Andromeda devices by having free-form window management feature."

The fact that Google is working on merging Android and Chrome OS is hardly news, but as more and more details come out, it seems to indeed be the case that Google is working on not just a smartphone operating system or a tablet operating system, but a full-fledged laptop/desktop operating system, complete with the kind of freeform window management we've come to expect from operating systems like MacOS and Windows.

Two independent and reliable sources have confirmed to us that Google is planning a new Pixel laptop to be released in Q3 2017. The project, known internally as 'Bison' and by the informal nickname 'Pixel 3,' will likely be the first brand-new device to showcase Google's combined Android / Chrome OS 'Andromeda' operating system in a laptop form factor. Bison, then, would be the culmination of years of work by Google's Pixel team and Google's Android and Chrome OS teams.

We are extremely confident Google plans for the device to run Andromeda. We are also confident that Andromeda is a completely distinct effort from Google's current campaign to bring Android apps to Chromebooks, and that Bison would not be marketed as a Chromebook. Android apps on Chrome OS descended from the ARC project, while Andromeda is a much larger, more ambitious initiative that is being pursued via merging Chrome features into Android, not vice versa. As such, it would be more accurate to say Bison will run Android than Chrome OS, and could finally be Google's internal commitment to releasing Andromeda.

Taking all this into account, a tweet that came out late last week from Hiroshi Lockheimer, SVP of Android, Chrome and Google Play, is quite telling: "We announced the 1st version of Android 8 years ago today. I have a feeling 8 years from now we'll be talking about Oct 4, 2016."

Much like Apple's similar efforts, I'm excited about what's happening on the Android side of things. It's clear by now that Google has very ambitious plans about moving Android forward and scaling it up to work on not just phones and tablets, but on laptops and desktops as well. Up until relatively recently, such endeavours would've been futile, because 'new' operating systems could never challenge the hegemony of Windows and OS X, but in today's world, where more and more especially younger people no longer rely on staples like Microsoft Office, or could get by just fine with the surprisingly good Android and iOS versions of Office, there's an opening for the laptop/desktop world to be shaken up.

Now, a lot of this will, as always, depend on execution. I wouldn't be at all surprised to see Andromeda take a... Less laissez-faire approach to OEM and carrier customisations, and a more Chrome OS-like update policy (which is entirely free from meddling). There's also the question regarding Andromeda's relevance on phones - will it exist alongside 'classic' Android, or will Andromeda replace Android on phones and tablets as well? My guess would be yes - why unite Android and Chrome OS only to end up with another split - but that raises a whole bunch of other questions about possibly docking phones and using them with large screens and other input methods.
